To-aZZ whom it may concern:

Be it known that 1 Grnsnrrr. F. PINsU'rI, a citizen of the UnitedStates, residing in the borough of Manhattan, city, county, and State ofNew York have invented an Improvementin Machines for Grinding GlassBottle Stoppers, of which the following is a specification.

This invention relates to a'machine for grinding the stoppers into thenecks of glass bottles. As is generally understood, glass bottles ascommonly employed for medirinesj, chemicals. pei' fiiinei g' and:various other substances, are provided with glass stoppers which" areground to place in the necks thereof. Heret0fore,so'far as I am Iaclutch pulley 21*assoc1ated with aware, it has been rnstomary to grindthe stoppers into the necks of glass bottles'by manual operations, andthe object of my invention is the provision of a machine for doing thiswork. vention, the apparatus preferably comprises a feeding mechanismupon'which the bottles are placed'and by which the bottles are conveyedto positioir in which the stoppets are ground to place in the necksthereof together jwith means for holding the bottles during the grindingoperation, de-' vieesfor gripping the stoppers while being ground toplace, means for producing a relative turn movementbetween each bottleand its stopper as well as an intermittent removal of the stopper fromthe neck ofthe bottle during the grinding operation, and means for"supplying a suitable abrasive material to the' neck of'the bottle duringthe grinding operation, all of which will be hereinafter moreparticularly described.

In the drawing: I

Figure 1 is a side elevation illustrating my improved machine forgrinding glass stoppers into the necks of bottles. i

Fig. 2 is a plan of the same.

Fig. 3 is an enlarged plan view illustrating the bottle retaining deviceand Fig. 4% is an elevation of a portion of the frame of the machine ndthe cam members by which the bottle. retainingdevices are operated.

As will be seen by reference to theidraw- I ing in carrying out thisinvention, the ma chine embodying the same comprisesv a frame, portionof which is indicated at 10 and which as will be understood may bemounted upon any suitable base In suitable positions onthe frame of themachine Incarrying out the in thereare bearings '11 and 12 in which a"drive sh'aft113' is journaled. On the drive shaft 13 on one side of theframe there is secured a pulley 14, by means of which through a suitablebelt thedrive shaft is driven. Onthegsame side of the frame as. thepulley 14c and'preferably at the extreni ity of thedrive shaft 13, thereis a worm indicated at '15. On the'opposite side of the frame aclutchcollar'16 is mounted on the drive'shaft 13'. This" clutchycollar 1"6 isoperated by a lever 1-7 pivoted at one end as indicated at 18in abracket '19 which is securedto the" frame 10; In the clutch collarlfithere is apin' 20 adapted to engage in a recess provided therefor in thehubof' which there is a sprocket'whee'l 22. Suitably secured to thefra'melO there are brackets23 and 24, extending between which I andjournaled thereinis ashaft 25. Onthe shaft25 there isa' gear 26' meshingwith the worm 15 so that through these mein'bers' the shaft 25 is turnedfrom the drive shaft naled a spindle 31. At the upper end of'the 32,while at the l'ower end of the spindle 31 there is mounted a roller'83bearing against the faces of the cam 28. "In the revoluble table'32there isa plu'rality of curvedslots 84 each adapted to receivea pin 36carried 85 spindle '31 'thereis secured a revoluble table by areciprocating rod which moves in a 7 suitable guide provided therefor,in the bracket .24. Adjacent its outer end, the re- 7 ciprocating rod 35is provided with a'pin 38 to which one endofa-lever 37 is pivota-llyconnected. The lever 37 is pivotally mounted as indicated at 39 in thebracket '24 and at its opposite end is provided with a roller- .10bearing against the face of the cam 29.

of a spring 41 or'otl'ierwise acting against the end of the rod 35 as isclearly indicated in Fig. 1 of the drawing. Also at the inner end oftherod35 the same is provided with a latch member 42 adaptedto enterslots 43 in the periphery of the revoluble table 32.

hereinafter de- The roller40 is normally maintained in po- I sitionagainst the face ofth'e cam by means 49 ca 7 at 51. The base 52 of eachbottle re:

responding: disk by 51311115155 blocks is indicated diagrammatically inFig. 2 and as they are all similarly constructed,

only one of them will be described.- Each:

block 44 is provided with a bore adapted to receive a plunger 45 whichrests upon a sprin 46 extending between the inner or lower en of tlieplunges fllldlthfi base of the bore in the block. Each plunger 45carries a disk. 47 in which there is a recessor socket 48. a h disk 47thereis a bottle holder or re: mm erferably made in halvesind catedatr1950. pivoted to one another as indiflan ,58andthe part50 with acorrespond ing ange 59. These flanges-58 and 59 are provided withopenings through whicha boltgfilis; passed. Surrounding "the bolt 60,

there is a spring 61 extending between a:

washer 62 bearing against the flange 58, and

a washer 63 hearing against a nut 64 at the extremity of the bolt sothat the action of the spring is normally to maintain the'parts' ta-and; 50 of the bottle retainer in their clflflfldwpositions; Pivotallymounted in the flange 158 there is a lever 65. The arm 66 of this leveris wedge-shaped and extends and lies between the flanges 58 and 59 sothatby movingthe arm 66 on its pivotal I ..'poi1nt, the flanges 58 and59. are spread to open the parts of the retainer when the arm 66is swungfrom left to right, as indicated at Figs. 1 and3rtomove the parts of theretaineregainst the action of the spring 61,

whereas whenthe arm 66 is moved in theopposite directiornth'e flanges 58and 5,9 are forced toward one another by the action of the spring 61 tocause the parts of the retainer to close uponthe walls of a bottle tohold the same in place. In order to operate this bottle retainer, thereare cams 67 and 69 secured respectively in lugs 68 and 70 on the frame10. As will be apparent by reference to Fig. 4, when thearm rides up onthe cam 67 due to a partial revolutionof the table 32, the wedge-shapedarm 66 will be forced. between the flanges 58 and 59m spreadthe parts ofthe retainer. whereas whenthe arm 65 is forced downwardly by the cam 69the wedge-shaped arm will be withdrawn from the flanges 58 and 59permitting the spring 61 to close the parts of the retainer.

As will now be understood, the revoluble table 32 is turnedintermittently through partial revolutions to successively bring thebottle ratainerintothe position to close the same upon the bottle, andwhen closed, the bottle will be in a position in which the stopper isground toplace in the neck thereof. At the same time when in thisosition through the reciprocation of the spindle 31 70 by means of thecam 28; the bottle will be raised and lowered any desired number oftimes to move the same into and out of contact with the stopper duringthe grinding operation. When thus raisedtilthe table will be free fromthe pin 36 and, rough the action of the spring 41, the rod 35 isreturned to its normal position in which the roller 40 bears against theface of the cam 29.

When the table 321's again lowered to its normal position, the pin 36will enter the 'next succeeding slot 34 in the table 32 so that when thenose of the cam. 29 comes into contact again with the roller 40, the

rod 35 will be moved from right to left 35 again as indicated in Figs. 1and 2 and the table turned another partial revolution.

I also employ a lever 68' which is pivot,-

ally mounted in the bracket 23 as indicated at. 69', and is fitted witha roller 70' adapted to bear against the face of. the cam 27. At itsopposite end, the lever 68' is provided with a slot 72 through which ispassed. a pin 73 mounted on a aft 7 4 which is journaled in bearings75and 76. The shaft 74 is provided with receptacles 77 from each of.whichextends a chute 7.8, the purpose of which will. be hereinafterdescribed, it bsin understood that the roller 70' is maintain in contactagainst the faces of the 1111127 by a spring 71 or otherwise, and thefunction of the lever 68? is to reciprocate the shaft 74 and thereceptacles 77 and chutes 78 carried thereby.

Mounted in the upper portion of the frame 10, there is a shaft 79, andfitting over a portion of the shaft 79 there is a sleeve 80. On one endof the sleeve 8flthere is a clutch ,pulley 81 carrying a pin 81, and onthe opposite end of the sleeve there is a bevelgear 82. Meshing with thebevel gear 82 is a bevel gear 83 secured on a shaft 84 journaled in thebearing 85 which forms part of the upper portion of the'manhine.

()n the shaft84 there is also a spur gear 86 meshing with a spur gear 87secured to a sleeve 88 which is journwled in a bearing 89 forming a partof the upper portion of the machine. Suitably secured to the lower endof the sleeve 88 there is a chuck head 90, while between the-lower endof the bearing 89 and the chuck head 90, I prefer to employ a suitablebearing indicated at 90'. Extending through the sleeve 88 there is ahollow shaft 9L, and within the hollow shaft, a rod 92. The hollow shaft91 and the rod 92 extend also through the upper portion of the frameofthe machine and through a cross bar 93 which is suitably fixed in theupper portion of the machine. Above the cross bar there is a bearing 91and on the upper end of the hollow shaft 91 there is a nut 95 adapted tobe turned down against the upper member of the bearing 94, while on theupper end of the rod 92 there is a nut 96 adapted to be. turned downagainst the upper end of the hollow shaft 91, so that the positionofithe hollow shaft is vertically adjustable relatively to the chuckhead; and the rod 92 is vertically adjustable within the hollow shaft91.

In the upper portion of the machine, there is also a gear 97 secured ona cross shaft 98 which is journaled in bearings 99 in the upper portionof the frame of the machine. The gear 97 meshes with a worm 98 providedfor this purpose on the shaft 79, so that the shaft 98 is turned fromthe shaft 79 through the worm 98 and the gear 97. On the shaft 98 thereis a cam 100 and running on the face of the earn 100 is a roller 102mounted on a trunnion 101 which is suitably connected to the hollowshaft 91 so that the hollow shaft 91 and the rod 92- F are verticallyreciprocated by the cam 100 through the rollerI-102 which is maintainedagainst the face of the cam by a spring 103 whichextends between a"portion of the upper {frame oft'he machine and a collar 102 secured inanyone of a number of; positions adjacent the lower end of the hollowshaft 91 within the Below the collar 102i af grooved collar 101' isfalsomounted onthe lower end of the hollow shaft 91 in a position tolieivithin the chuck head 90; this collar 101, beinginounted to turnfreely on the end ofthehollovv shaft 91.

Adjacent the lower extremityof the hollow shaft 91, there is fixed adislr510 1, and in order to normallyi' inaintain the revoluble collar101 against' the fixed" collar 102, I employ a spring108 extendingbetween a shoulder on the revoluble collar 101 and the disk 10 1 Withinthe chuck head 90, I employ ajseries of. hell crank levers 10 1, eachpivotallymounted therein at 105, so that the extremities of the shortarms of the bell crank levers engage in the groove of the revolublecollar 101 while the ends of the long arms of the bell crank levers arepivotally connected to grippers 106 adapted to move in slide ways 107.These grippers 10G, irrespective of their number are adapted toengagethe stopper of the bottle soas to hold the same in the properposition during the grinding operation.

On the shaft 98, there is also mounted a cam 108. Bearing against theface of the cam 108, there is a roller 109 mounted on a spindle 110secured at one end ofa rod 111. The rod 111 is journaled in bearings provided therefor in extensions 112- and 113 in the upper portion of theframe of the machine, while at its opposite end, the rod 111 providedwith an extension arm 11 1 turned at right angles thereto and throughwhich the shaft 79 passes. On the shaft '7 9 adjacent the arm 114:, aclutch pulley 115 is suitably secured. This clutch pulley 115 isprovided with a recess 116 adapted to receive the pin 81 on the clutchpulley 81 and the rod 111, and associated parts are maintained inposition with the roller 109 "bearing against the face of the cam 108 bya spring 1.17 surrounding the shaft 79and extending between the clutchpulley 11.5 and the hub of asprocket 118 which is also secured on theshaft 79 in the same plane as the sprocket 22. Passing over thesprockets'22 and 118 there is a chain 119 so that the shaft '79 isdriven from the shaft 13 through the clutch pulley 21, when the same isconnected to the collar 16 so as to be turned by the shaft 13.

Suitably secured to the extensions 112 and 11301? the frame, there isa-table 120 adapted to carry thereceptacle 121- and 122, one of which.contains aquantityQof powered sand or other suitableaabrasive materialand the otheris supplied with water. Extending from the rece'ptacle121is 'a-pipe 123-which may be suitably divided'xto supply the 'aln'asivomaterial to the receptacles 77, and extending from the receptacle 122 isapipe12 1 which also may :be suitably divided to convey the necessarywater to the chutes 78 to be com bined with the abrasive matcrialwhensup- 1 plied to the neck of; the bottles for the grind ing operation,-itbeing understood of course that any suitable means may be employed toregulate the flow of the abrasivematerial through the pipe 123 as wellasthe fiOWiOf thefwater through thepipe 124; l wi In the, operation ofthe hereinbefore described apparatus, the bottles into the necks iofwhich'the stoppersareto be ground, are placed in tl1e"l)0ttl8l10lCl8IS 19 while'thc same are in anopen position, and assumingthe lever 17 hasbeen thrown to connect the clutch pulley 21, thedrive'shaft liS aswell as the shaft 79 will be continuously revolved.The revoluble table 32 :is intermittently moved a partial revolution tosuccessively bringa pair of bottleholders into the grinding position.This, as hereinbefore described, is eilected through therod 35 which isreciprocated intermittently by the lever 37 and the'cam 29 acting upontherevoluble table by. the pin 36 successively engaging the slots 34:.As each bottle holder is brought into the grinding position, the lever iAll gri pal-shave engage the bottle stopper, the

is releasedfrom the-slot 34 in which it was engaged, and through theaction of the spring 41, the rod 35 is returned to-its normal positionwith the roller 40 against thefaoe of the cam 29, in which position thepin 36 is so placed as to be receivedflin the next succeeding slot 34'when the revoluble table 32 is again permitted to descend.

When the rod 35 is returned to its normal position, the latch member 42enters one of the slots 43 in theperi hery of the table so as to lockthe same in p ace. With the parts in these positions, as will beunderstood, the

i being move these parts carrying with them the grooved collar-@101which is moved upwardly against the action of the sprin 103','so thatthere is. made possiblea yiel ing gripping action between the grippersand the bottle stopper when engagedtherebyy r a r Inaddition to thisyielding action of the gri rains, it will be apparent that by shiingythe collar 102" on the hollow shaft 91 theextent of the movement ofthe gripperswmay be adjusted to accommodate the grippers to as per headshavingv varyingameters and t at this will in no wise interfere with 1the yielding action of the grippers in. engaging the stop r heads. Afterthe rol M109 runs on to the depressed portion of the com 108 permittingthe clutch pulley 115tobe engaged with the clutch pulley 81 therebyturning the sleeve SOandthrough the bevel gears 82and 83 as well as thegears 86' and 87 causing the sleeve 88to turn and with it the gri rmembers 106 and the bottle stopper. hile thus engaged, the revolubletable and the bottle are reciprocated several times through the actionof the cam 28 and the roller 33 so that while being turned, the bottlestopper is inserted and withdrawn from the neck of the bottle, duringwhich time, the shaft 74 is rcciprocated so as to supply a predeterminedquantity of abrasive material and water to the neck of thebottle for thegrinding operation. After the inding operation is completed, the

revolllble table 32 is turned another partial revolution, and in sodoing, the lever arm ridesup on the cam.67 forcing the arm- 66 betweenthe flanges 58 and 59 so as to open the. parts of the bottle holder,making it possible to remove the bottle. Furthermore, as will-beunderstood, the adjustment of the position of the hollow shaft 91 is toeffect a relative movement of the gripper members 106, depending ofcourse upon the size and,

diameter of the stoppers to be engaged, while the adjustment of the rod92in the hollow shaft 91 is to accommodate the grinding of stoppershaving'diiferent length heads, inasmuch as the upper portion of thebottle stopper contacts with the lower end of this rod 92 during'thegrinding operation. It will furthermore be un derstom'kthat the partsmay be so adjusted that a partial grinding of the bottle stopper in theneck of the bottle may be effected in the first grinding position andthe grinding finished in the second grinding position in the machine asillustrated or the entire operation may be completed in one position,that is to say, a stopper may be partially ground to position in theneck of its bottle when the parts are engaged by the first grindingdevices, as illustrated, andthe grinding completed after the nextshifting ofthe bottles and stoppers b the second set of grindingdevices, as illustrated, or the conveyor or revoluble table may beshiftedso that pairs bottles and stoppers are brought to the grindingoperation andthe grinding of the stopper in the neck of each bottlecompleted at one 95 operation. Furthermore it will be understood thatwhile I have herein shown and described a revoluble table as a conveyorfor the bottles and stoppers to carry the same to-the grindingpositions, an" form of suitable conveyor for moving t e bottles and"stoppers to positions to be ground, may be employed withoutdepartingfrom the nature {UK spirit of this inventioni As hereinbeforedescribedand illustrated in the drawing, the present invention has beenmade to relate to an apparatus for grinding the glass stoppers into thenecks of glass bottles. Of course it will be understood however, thatthe invention is not specifically so limited, because in carrying outthe same, it is quite possible to grind the stoppers and the neck of thebottles into such a uniform manner as I believe to make theminterchangeable, which heretofore has not been possible. To this end ofcourse, in so carrying out'the invention, the stoppers may be turned inand ground by a suitable unit or grinder comprising a member in whichthere is a grinding socket provided and the necks of the bottles may beground by turning therein a suitable standard plug made tothe size ofthe stopper which is to be employed withthe bottle. In either or botheventsof course, the required abrasive material is furnished to theparts during the grinding operation.

In so carrying out the invention, instead of employing the holder forreceiving and gripping the bottles any suitable socket member may beheld in position in the apparatus for grinding the stoppers, or insteadof gripping the bottle stopper. a grinder plug may be substituted. forthe bottie stopper and used as a grinder for the necks of the bottleswhich then may be placed and conveyed 'to position for thegrindingoperation in the samemanner as the bottles are in the apparatus'hereinbefore specifically described.
